A ball screw drive comprising a spindle nut () that can be disposed on a spindle (), said spindle nut () comprising on an inner periphery, a ball groove () that is arranged along a helix and defines a load-bearing channel () for balls (), an external deflector () arranged outside of the spindle nut () connecting the two ends of the load-bearing channel () endlessly to each other for deflecting the balls () from one of the two ends of the load-bearing channel () to the other of the two ends of the load-bearing channel (), a drive pinion for driving the spindle nut () being arranged on the spindle nut (), wherein the external deflector () is arranged at least substantially within an axial length of the drive pinion.

Ball screw drive

Ball screw, between the spindle nut () and threaded spindle () of which at least one ball chain () formed from balls () rolls in each case along a ball channel () which is delimited by ball grooves () formed on the spindle nut () and on the threaded spindle (), the ball chain () being deflected from one end of the ball channel () to a start of this ball channel () in deflection portions of the ball channel (), one or more spring elements () arranged in the ball chain () between balls () of the ball chain () exerting a pressure force on the balls () in the axis of the ball chain ().
